The storage arrays receive regular updates from Dell. Often, these are not needed but some are deemed urgent. These instructions will help you update the firmware for both the controllers and the disks.
There have been EMP errors coming from the management controller. These errors are informational only and are resolved within five seconds but will trigger a notification of hardware or disk problems. These appear to be fixed in the GT280R011-01 release. The errors may call out alert condition on a "current sensor", "voltage sensor", "temperature sensor", or other internal sensors.
The disks have been reported as Failed but are good. Replacing a reported failed disk may not solve the problem. The firmware should be updated to at least the Hitachi (HGST) NM10 release.
This is for both the Broadcom U144 and U184 storage arrays. Dell knows these as ME4012 and ME4084 or just ME4.
The most recent firmware is kept by Dell in their support library. You will need to download the controller and the disk firmware. These can also be done separately, as needed. There are no interruptions for the controller update but the disk update will require that all disk traffic be stopped.
For both the controllers and the disks -
For the controller firmware update -
To update the disks, you will need to stop all I/O traffic to and from the disks. Allow 30 minutes total to shutdown the traffic, update the firmware and start the Security Analytics sensor again.
This completes the firmware update.
